Center holed beads require a little more thought to use in jewelry designs. Here is a simple wire work flower earrings tutorial by Lesley Watt of THEA Jewelry. A sweet design with little wire tendrils. You will have to scroll down a little to find the tutorial.
Lesley used balled headpins to create both the loop which hangs on the ear wire as well as the wire tendrils. Although she used flower beads, any center holed beads will work too.
If you continue scrolling down, you will also find her wire macrame earrings which I mentioned before.
